Question

Why is electric power transmitted at high voltage?

a) To decrease energy loss.

b) To increase electrical resistance.

c) To reduce the voltage drop.

d) To maximize current flow.

Answer 1

Electric power is transmitted at high voltage to minimize energy loss during transmission by reducing resistive heating and joule losses.

Step-by-step explanation:

Electric power is transmitted at high voltage to minimize energy loss during transmission. When power is transmitted over long distances, using high voltage reduces the current flowing through the transmission lines, which in turn reduces the resistive heating and joule losses. This allows more power to be transmitted efficiently.
